it's well known cars in US (even Japan) are always a good .3 -.5 sec quicker down the strip compared to what you can achieve on aussie soil - like for like

i think the main reason is the way they measure roll out, which on a hard launched awd car is a noticeable time advantage

Martin's 10.3 for eg would be close to a 10 flat on a US drag strip

a more accurate comparison when looking at acceleration times from different countries is the 60-130mph

Its easy to make big power out of these stock engines. The trick is to keep the stock rods inside the engine over the vehicles life......

Getting a one-off drag number isnt so hard if you put your mind to it. It certainly impresses a lot that dont understand the risks, and the massive potential cost, involved

Why you would spend 10's of thousands of dollars on modifications for an extra 0.1 to 0.3 of a second over a 1/4 mile is beyond me. Especially with these kind of results with just a mid pipe and tune. A good video this one, some nice shots taken from inside and outside the car.

That's exactly right. People who spend that kind of money to get such a miniscule increase in performance (which they would hardly ever use anyway) don't do it because it actually makes any sense, they simply do it because they can! :yes:

Sorry off-topic.

Hey Domino, how did you install your rear diffuser fins? Did you have to drill the carbon panel under the car?

I like the look and should reduce soot on the back of the car. Did you find any difference?

Thanks.

i get absolutely zero soot daily driving on e85, that's the best solution to reducing carbon emissions..... or Martin should have the new injector end pulse tables for cobb which may help on 98 Ron

im not sure what part you're referring too

I am running the top racing carbon lower diffuser which replaces the oem part

These are the hks kansai diffuser fins I bought a while ago. I haven't installed them yet, looks like you have to drill into the oem carbon diffuser. I had to paint the leading edge on both pieces matte black as they were quite rough looking with excess resin

but i can't see how either part could possibly reduce soot

Hey Dom -

Yup, that's the one - the Kansai diffuser fins. I thought you had installed that (saw your NAGTROC post).

Apart from the the good looks, the diffuser fins should extend the turbulent wake further behind the car at high speed, therefore reducing accumulation of exhaust output onto the rear face of the car. It should therefore reduce drag and improve rear downforce in conjunction with the rear upper spoiler.

^ Whoop-dee-do!

What would that cost the average consumer... just to put things into perspective.

Around $5K all up is what most GTR retailers will sell this kind of package for depending on existing mods already in place (ie. exhaust etc). and what brand parts they use. Not bad for a daily driven 10 second car :)

Many different kits from many different parts upgrade manufacturers to do this on these great cars. GTRs are a great base, which is why we all like them so much here.

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
